I have added a Ajax tab control into my page and first tab includes the data entry part to a table and second tab is update the data in a table (Database).
The problem is in first time when I click submit button without filling any details it shows the error messages (I set required fied validators) but next time it didn't show the error message but it not submit the page. So I understood that the validation controls are worked but it doesn't show the error message. Is there any solution?

I have a panel (say, panel1) inside another panel (say, outer-panel)....The panel1 is visible only when a checkbox is checked in the outer-panel. I am using script manager, update panel and trigger to do this.
Now I have many text boxes in the panel1. I have to put a validation on all the boxes.
I tried to test this by putting validation on 2 boxes and this works fine on my local machine. When I put the same logic on the server, it does not. Of course the page on my local machine has fewer text boxes compared to the page on server. But I do not understand why the same logic works on my local machine and does not work on the server.
The page on the sever is a very long one and also it has a captcha control..... when ever I try not to enter text in one the text boxes which has validation and then hit submit...it redirects me to another page with out prompting for the validation error.

I am creating dropdown controls in code behind. in some conditions I need to add validation control to dropdowlist. But Validation not firing when I submit button.
If mQuestion.RequiredToAnswer = True Then
Dim mValidator As New RequiredFieldValidator
mValidator.ControlToValidate = mDDL.ID
mValidator.InitialValue = mDDL.Items(0).Text
mValidator.Display = ValidatorDisplay.Dynamic
mValidator.ErrorMessage = "* Required!"
mTableCell.Controls.Add(mValidator)
End If

I have an upload control inside a panel and I am wanting to restrict the file types. I have found the following regExp but I'm unsure where to put it?
ValidationExpression="^(([a-zA-Z]:)|(\{2}w+)$?)(\(w[w].*))(.doc|.PDF|.gif|.jpg)$"
Does this go into the 'ValidationGroup' within the upload button?

I am trying to implement validations for a jQuery pop-up which is placed inside an update panel. I am facing problems using validation controls and I presume its because oft he ClientScriptManager it uses. I read in the FAQ section [URL] that we need to download and apply a hotfix to solve this.

I have written the following logic in the pageload method,

I have a page with three update areas, Create, Edit, and Delete. The controls that do these three functions are inside separate update panels so when I'm doing Create, I only fill controls inside that updatepanel. Problem is I'm using asp validation controls on all the controls in the three areas. Therefore, when I press the "Go" button in the Create UpdatePanel, the validation fails on the empty controls in the other two area. I hope I'm explaining this well. The behavior I would like to see is that only the controls contained in the updating panel would be validate.

I have a Gridview with a number of Template fields, where the values are all binded to a DB.
I can handle the validation in the codebehind (C#) fine, as far as that singe control.
BUT
I want the validation to be dependent on one of the controls in a Different TemplateField
ie.
Template A
Template B
Template c
Template B & C dependent on Template A

I'm using the ASP.Net Validation controls and I want to display the Validation Summary in a JQuery Dialog instead of the native javascript alert messagebox. I've found this solution (aspsnippets) by overriding the clientside WebForm_OnSubmit() function:
<script type="text/javascript">
function WebForm_OnSubmit() {
if (typeof (ValidatorOnSubmit) == "function" && ValidatorOnSubmit() == false) {
$("#validation_dialog").dialog({
title: "Validation Error!",
modal: true,
resizable: false,
[Code] ....
The WebForm_OnSubmit() function is being rendered by the BaseValidator control and in the form tag te following attribute is being added: onsubmit="javascript:return WebForm_OnSubmit();
I am running into a problem on a page which has an UpdatePanel. The input field with the validator (1 to make it simple) is in a Panel within an UpdatePanel. The Panel is set to Visible=False at the first Page Load. There's a button inside the UpdatePanel which makes the Panel with the Validator Visible.
When this happens, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered because it's an AJAX callback and the form tag is outside the updatepanel (in a master page), so the validation summary will not be shown in the jquery dialog.
Validation is being performed, so the validation summary wil be shown in a div on a page, but the validation is not being called by the WebForm_OnSubmit() function in this case, because it's not being rendered.
Here's the markup of the page:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="btnNew" runat="server" Text="New" />
<asp:Panel ID="pnlEdit" runat="server">
<table>
[Code] ....
So, when the validators are not visible at the first load and they will be made visible by an AJAX callback, the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag are not being rendered on the pag. Because of that, the WebForm_OnSubmit() function will not be called and the validation summary will not be shown in the JQuery dialog (although it is being shown in a div on the page). How can I get the Validation Summary to be shown in de JQuery dialog in this case?
Is there another function that has to be overriden for this case? I know I can use a Full Postback for the New button and then all the stuff needed is being rendered on the page, or I can make the panel not visible by using a style, but I don't prefer that because there are a lot of pages with this situation.
One solution is to use a dummy textbox with a dummy validator (with a dummy validationgroup) of which I set the display to none. Then this dummy validator will cause the the WebForm_OnSubmit() function and the onsubmit="javascript:return WebForm_OnSubmit(); attribute of the form tag to be rendered.

I have a small a problem with my navigation control. My navigation control has many menuitems. But here is just an extract to explain my problem.
<asp:MenuItem Text="Customer">
<asp:MenuItem NavigateUrl="~/CustomerLogin.aspx" Text="Log In"></asp:MenuItem>
<asp:MenuItem NavigateUrl="~/CustomerProduct.aspx" Text="Product"></asp:MenuItem>
<asp:MenuItem NavigateUrl="~/CustomerInformation.aspx" Text="Information"></asp:MenuItem>
</asp:MenuItem>
so when i put my mouse on Customer, the child menuitem drops vertically. The problem is I have a panel on the page which I use Gray Color as it background color and child menuitems are hidden behind that panel. Is there a way to show the menuitems on top of the panel beside moving the panel further down?

I have 2 text boxes in which I am comparing the numeric value of one to the other. At first it works fine and I get the appropriate error message. But eventually as i plug in different numbers although I should be getting an error message I stop getting one. Is there something going on behind the scenes to fire the error message than I am unaware of. Also the error message fires some time when the value is less than the value of another control and equal to the value. I only want it to fire when it is less than the value of the other control.
